A.) The first student explains the first arrow must demonstrate how the base pairing rule is being used to replicate a strand of DNA since the complementary pairs
are being lined up for semi conservative replication. The second arrow must
demonstrate the process of transcription since the DNA is being read at the
ribosomes and the monomers of protein are being connected.

B.) The second student explains the first arrow must demonstrate how the base
pairing rule is being used to build a single strand of RNA from the DNA. The
second arrow must demonstrate the process of transcription since the DNA is
being read at the ribosomes and the monomers of protein are being connected.

C.) The third student explains the first arrow must demonstrate how the base
pairing rule is being used to replicate a strand of DNA since the complementary
pairs are being lined up for semi conservative replication. The second arrow must
demonstrate the process of translation since the RNA is being read at the
ribosomes and the monomers of protein are being connected.

D.) The fourth student explains the first arrow must demonstrate how the base
pairing rule is being used to build a single strand of RNA from the DNA. The
second arrow must demonstrate the process of translation since the RNA is
being read at the ribosomes and the monomers of protein are being connected.

i believe the answer is a or 1

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
